Steve, what do you mean by scratch and stick? It sounds pretty self explanatory, but i've never tigged. Is it a bad thing? What is the alternative to 'scratch and stick'? It sounds like a i can mig/ flux cored with this thing too. On a scale of 1 to 10, where would you rate this unit?
Thanks, john401Scratch start TIG as opposed to a high frequency arc start. It is kinda similar to the way you start an arc on a regular stick/welding rod.Yes, it will run a wire feeder if the feeder is capable of running off constant current (cc). Feeders run smoother off of constant voltage (cv), though. Some of the 304's are cc/cv.
They'll run everything.If you haven't gone to Miller's site and checked out the owner's manual, you should do it. It will answer a lot of questions as to specs and capabilities. Make sure you put in the serial # of the machine to get the correct manual. There can be some differences in the model configurations.

Yes iam a proud union boilermaker. Boilermakers local 500 portland oregon.
A founding member. I rate the miller emt as a great choice a 9. To me a welding machine is a welding machine. I like inverters better then the regular old welding machines.
For tig welding I hate machines with a hot start. For that matter I dislike hot starts for anything then maybe stainless stick welding. So welding tig on the regular old welding machines requires you to weld on the high range. By doing this often you cant get the machine to adjust low enough to tig weld x-ray quality work. This is why I like inverters over regular machines.
Working in the field you use alot of different machines. The company I work for most of the time psf industies uses miller machines. For x-ray work we use the miller xmt.
For non criticial work we use the big old blue miller machines. It is best not to use your best machines for cabon arcing.
This ruins them. Lift tig lets you put your torch on the work then lift up and start welding. I generally dont use this feature.
I like inverters for ln25 siutcase wirefeed welding; Cv runs them feeder so much better then cc. At my house i Ihave a lincoln 225 ac/dc idealarc welding machine the old red ones with the round top. I use this for stick welding and tig welding. I also got a century 110 fluxcore wirefeeder( wish I had a gas hook up) that comes in handy for quick welding jobs. I bought this unit used new in the box at a garage sale for 100 dollars. For field work we use a dry tig set up no water cooling or foot pedals.
Thinks all that stuff isnt really needed. The xmt in my opinion is the best stick welder on the market unless you want to use an engine drive(sa 200 or clasic 300). I use my xmt all the time in the shop for stick and gouging, it has never gvin me a problem i have also used it for thicker tig work never really anything below 100 amps( i use a ck 250 amp water cooled torch) and even just scratch starting i have a gotten excellent welds using it as tig. Also alot of people have concerns aboyut running it on single phase, the olny thing i have incounterd is a lower duty cycle, which doesnt even matter unless your running real hot. Hey, thanks to all of you guys. It's awesome having all of this knowledge and experience just a click away. I think i'm going to go with the xmt.
Now i just have to check if it is a cc or cc/ cv. If it is cc/cv, it's a done deal. Wild bill actually answered a question i was going to ask on this board. I wasn't sure if it was single phase as well as three phase. The machine is going in my garage, so it would have to be single phase.
Glad to hear that lower duty cycle is the only sacrifice.
